  • Could lead to an increase in output power of up to 80% and could eliminate up to 70% of NOx emissions as the operating temperature is lower than that of combustion
  • Supports extensive current and future research into low carbon energy generation, integrated energy systems and hydrogen economy
  • Offering a fuel cell of this kind at the facility creates the opportunity for R&D and innovation on this new carbon capture solution, including opportunities for research into the use and generation of green hydrogen, bioenergy with carbon capture and storage (BECCS) and across the full carbon capture, utilisation and storage (CCUS) chain for both power and industrial applications
  • Thanks to our flexible, plug-and-play approach, research can be undertaken not only to understand more about the capabilities of the fuel cell itself, but also its ability to converge with bioenergy processes and sustainable aviation fuels research. The fuel cell will also utilise hydrogen generated on-site from renewable electricity and, as with other equipment in the facility, the fuel cell will be integrated through the smart energy system for system management and optimisation.

Biodiesel engine generator

  • The combined heat and power (CHP) biodiesel engine can use a range of liquid biofuels to generate green energy

  • The biodiesel system is able to support research into a variety of liquid biofuels, facilitating the assessment of key performance indicators and thus the innovation and development of cleaner liquid fuels
  • The facility enables quantitative research into fuels of different origins/quality, power conversion, operational parameters, etc.
  • Extensive system monitoring and data logging, including with the emissions monitoring suite, provides comprehensive data for system operation

Gas turbine

  • The Turbec T100 micro gas turbine is highly instrumented to allow monitoring of the whole gas turbine cycle (temperatures, pressures, etc.), including extensive emissions analysis from the exhaust
  • Conventionally fueled by natural gas, conversions are in place to fire a range of other fuels, including biogas
  • The system comprises of a single-stage centrifugal compressor (with a pressure ratio of 4.5:1), a lean, pre-mixed combustion chamber and a single-stage radial turbine
  • The generator and shaft rotate at up to 70,000 rpm to generate high-frequency electricity that is exported to the grid
  • The counter-current water-gas heat exchanger is used to recover thermal energy; overall, the system has an electrical output of100 kW, with a thermal output of 165 kW (electrical efficiency ~30%; total efficiency ~80 %)
  • The system has been modified to include exhaust gas recycle (EGR & Selective EGR), by which CO2 injections enable the examination of the impacts of recycling the exhaust gases on the combustion system, efficiency and emissions under different operating conditions
  • The significant dilution ensures high combustion efficiencies and low levels of emissions (CO, NOx, etc.)
  • Post-combustion CO2 capture research from the turbine system is available, since the flue gas pathway is integrated into the on-site capture systems
  • Fuel flexibility research means that we are also investigating including hydrogen blending and other sustainable alternative fuels into our system
